What master sizes are you after fella? Will see if I can grab an ex Supercar for you, complete with carbon foot shroud etc

[Marlin]

Whether hung or floor mount is VERY much dependant on the vehicle, and how you sit in it mate. I'd suggest waiting until you have a seat and wheel dummied into place and then make the call.

Floor mount is usually preferable and easier to adjust and service, but, some vehicles just don't suit them, and smaller cars are usually the most challenging.

Cheers Bris. I am told this is about where I will need to be. 5/8" front, 3/4" rear, 3/4" clutch.

But based on the Woo's advice I might be jumping the gun a little and might need to get the rest of the shitbox built first and leave this component till seats and tiller are all in place. Thanks for the heads up Woo. Is a component I havent dealt with before. I was scratching my head a little comparing the floor mount to the firewall style mounts. As oyu said the floor looked the easiest path for mounting, but may not suit the RX7 considering I might find myself sitting pretty hard against the floor to fit in the thing.

But Bris, I m always a sucker for a bargain. Let me know if you turn up anything.

[Marlin]

Try not to leave it as the "last" thing to go in. They're not a simple fit, and having intrusion bars etc in the road doesn't make it easier.

With the car stripped just try and envisage where the relationship between seat/wheel/cage will be, and take it from there.

Anyone know much about pedal boxes? Am guessing a floor mounted jobbie would be the go for the RX7? My gut feel is tyhe usual spend as much as you can afford to applies as it is an area you dont want to cut corners on. Any experience appreciated.

Seems quick research reveals you can get an OBP unit from the UK for a very reasonable price although a little googling reveals they may have their shortfalls. Dont want dodgey pedal feel and performance.

Then there is tilton 600 series for reasonable money.

Tilton 900 series for more.

Then AP for crack pipe money.

I've had an OBP unit, and i on sold it because the qulailty just waas up to scratch, so i bought a Tilton 72-603 and it's a great piece of kit..

pedalbox's really are a get what you pay for sort of thing!!

Room is the biggest thing, they take up a lot more than you think!, i had cut the floor on my GTR to fit it in..

the only other thing is, Tilton will quote you for the box, but it doesn't come with anything, you then have to buy the throttle pivot, and the balance cable

which is another $350 ..

[Darkside]

Thanks Woo and Jon. Great info. I was trying to get on to the seat etc early so I can mock up the cabin once the shell is stripped and tackle any additional cutting of metal or welding in any extra metal required when we do the cage so will try to get a feel for the pedal box then. If we have to do a hung one, I guess that would be the time when the dash etc is all out.

Thanks for the first hand feedback on the OBP unit Jon. I had a feeling they might have been a little flimsy and not quite up to the job but that confirms it. Had read there can be a bit of lateral flex in the pedals etc. Not ideal for something as important as brakes. :)Point taken on the Tilton as well. They dont look too badly priced until you add in the master cylinders, brake bias etc.But probabaly the best value of the decent gear. Gonna be a bit spendy but do it once do it right I guess.

Thanks again for all the input fellas.

We test fitted an AP floor mounted setup in the RX3 (that I will probably never finsh), and I just couldn't make it (and me) fit in the car, without cutting and welding the floor/firewall. Needed at least 260mm back from the pedal centreline. I noticed another rotary and a few other cars with exactly this done at High Country, but I don't think it is either legal or within the spirit of the rules..happy to be corrected if I am wrong?

I have used the Tilton firewall mount before with good results, maybe some firewall strengthening required though to stop flex. A friend fitted a "floating master cylinder" type firewall pedal box setup a few years back to an IP car. Cost over $5k from the US but gained over 1sec a lap at QLD raceway, so he was happy! Exchange rate should be better now.

There is some very useful info on pedal box setup etc on the Performance Friction website to do with angles, pivot points etc if you want to build it yourself?

[Marlin]

Our mate Hooch seems able to find Tilton gear at the right price. Holler before you buy BP.

Pretty much carte blanche from my reading of the rules, pedals free, with modifications permitted to be made for installation of same....limits of that work aren't defined....so go crazy with the angle grinder!

Believe bogan v8s are well entrenched in the version of IP in the west, but you'd be well advised to check out an Rx7 in that category if there's any around, it's nothing new there and might save a few pennies. The needle roller masters in some of the newer pedal boxes make the eyes water, price wise.

[PHaT MR30]

Have you considered Wilwood Blaise?

[Burgz32]

Smart buying got me my Tilton unit complete pretty bloody cheap..

Pedal box $620 (got the pedalbox and accl pivot through Tas performance Wharehouse down here, Luke's a top bloke..)

Accl pivot $190

Bias cable $65

Cylinder's $93ea 3 of 1x 5/8 1x3/4 and 1x11/16

and looked around at work for a fluid reservoir, so it was free!!!, some kind of old alfa thing..

Total just under $1200, plus around $300 for some new braided line's to plumb it into what i already have..$1500 is pretty cheap..

i only fitted mine to remove the ABS from my 32 GTR, and free up a heap of room in the engine bay, can actually get to my starter motor now,

it does lower the centre of gravitly...,

but if your gunna Build an RX7 it might be worth looking into swinging under dash gear, as i'm sure someone make's a bolt in kit....

I hadnt seriously looked at em. Although they always seem well priced out of the US. Will have a looksee...

Thanks Jon. It adds up but you got some keen pricing. Will have a sniff around on the IP forum too. Surely someone has crossed this bridge before. No point reinventing the wheel.

So Baw Baw sounded interesting on the weekend. Coupla casualties?? ABS failure??? *patiently waits for the incar to be uploaded*

No offence here but seemed to be a bit of a Steven Bradbury by Sammy?? To finish first, first you must finish. Top effort!! Consistent driving all weekend while others in front faltered. Lesson in that I guess.

[Roy]

The important thing that came out of the weekend was that Rugby Union men are tougher then AFL. After hours of debate we cleared the living room and wrestled! Union won!

[Marlin]

Yeah come on, when are we getting all the in depth analysis from the weekend. Heck, even from someone who saw it from the sidelines would be good!

Andrew..... Troy?

[paulR32gtr]

Vid is up on Snowy's youtube

Uneven surface, greasy road, power on causing back to step out?

isn't that just being gay?

[Marlin]

Unlucky for Snowy and Roy

Looks like a bit of trailing throttle oversteer, then hit a slightly wetter patch, and just not enough room to correct the big girl's slide

[R31Nismoid]

Was the road surface Ben, could see on the road where the inside wheel has lit up on uneven road surface and the left wheel was only semi touching the road due to a bit lip/hump in the road.

Car with a smaller width wouldn't have even noticed it really.

Great weekend overall though. The WRX that was leading had turbo or manifold gasket failure so unfortunate but not major in terms of damage. Then Traverso came off near the end into a tree (left hand front corner, sizeable hit) in the end section of the last session.

From a touring group point of view I had a ball. Nick was up there also (LotusGTR), had fun playing with him in his GT3

Tarmac Rally is certainly more my "thing" than circuit work, bug well and truly planted.

Went through ~75-85L of fuel, great fun.

Great work from Peter, Tim & Mountain Motorsports to get it up and running. Best piece of road I've driven yet.

[R31Nismoid]

Oh and Brisby is now known as "The Wombat"

[Darkside]

WOW. Goes from right to wrong in an instant. Hear what you are saying though Snowy. Setup does seem a little lively for a tarmac rally car. Lots of little slides out of corners. Hope the recovery today went well. Top job on the notes Bris. The car definately has pace. Look forward to seeing it back out there.
